Taking measurements and working on ESD modules
Measurements may be taken on electrostatic sensitive devices only if
• the measuring device is grounded (e.g. via protective conductor) or
• the tip of the isolated measuring tool has previously been discharged (e.g. by briefly touching
grounded metal parts).
